WASHINGTON – Credit unions are finding that net interest margins remain under pressure and it is becoming increasingly important to maximize the return from the investment portfolio. With that in mind, WesCorp and Callahan & Associates, Inc. will host a free webcast on looking at some investment portfolio "quick hits," as well as how credit unions can make sure they get the best return for a given amount of interest rate risk. In addition to net interest margin pressure, Callahan said "the flat yield curve also restricts the returns available from just extending maturities and makes every basis point pick-up in yield even more important." The webcast will take place 2 p.m. EST April 21. Featured speakers include Bob Burrell, WesCorp executive vice president and chief investment officer, and Jon Jeffreys, Callahan associate vice president.
